Application filed lllll'" 71 1.905' serial No' 270043 i' 'efal when@ it may concern: j

y Be 'it known that I, ALVIN S. Rnro'nEL, -a citizen of t lni'tedStates, residing at Point Marien', in t l county ci Fayette and State n-jljennsylvai ia, have invented certain new l and' useful improvements in lviachines for f Manufacturing Glassware, oi which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to that class of machines for manufacturing glassware wherein the article is partially formed by pressi ng and is then blown into inished form, and the primary object is to provide an improved niachine of simple construction for performing the forming operations rapidly, accurately, and unifor ly.

While the improved machine may be utilized for inanuiactnring various kinds of hollow ware, it is designed especially for the production of bottles. A While the'invention belongs to that gen- .erai'type ci' pressing and blowing machines i wherein the .melde are mounted upon a horizontally movable carrier and coperate with vertically movable pressing and blowing mechanism, .it differs primarily from Inachines of former construction in having the yforming mechanism move in unison with the mold-carrier, and in havingthe pressing and -bl'owin'g operations take place while the forming mechanism and carrier are thus mov- 1n further distinctive characteristic is that the advancing movement `of the carrier operates to move the press-mold out of operative position and the blow-mold into o erative position between the pressing and to the-end of the forming operation. :rf'

1 The improved machine is preferably em-` bodied jin a circular series of independently operating mechanisms, the number of which ma be varied as re uired to secure the bestV an most economica results. y

In the embodiment oi the invention herein disclosed, a base-2 is iormed with a central hollow boss 2, and uniting therewith is upright cylinder 3, which comprises an air-reservoir to which air under pressure is admitted through connection 3 from any suitable source. Inclosing and rotatable around cylinder 3 is tubular post 4 having a ball-bearing v 4 interposed between its lower end and boss 2. Secured to this post is the circular car- 'rier or table 5, the periphery of which is pro.- vided with casters 5 which travel on the ring-like frame 6, supported `by standard 6 rising from the base.

` 7 designates the circular `mold-supports which are arranged in a circular series on car- ,rier Each of these supportsis rotatably unounted on ball-bearings 8 and 8', and depending froin the center thereof'is a stem 9 is adapted to mesh with racks 1 1 and '11. supported; frame 6. ICarried by each of supports y7, at opposite sides of itscenter, is a` press-mold 12 land a divided blow-mold 13.

IOO

ally extending -arm 14 15", respectively,

each of which overlaps theunextended` end of the other slide. The adjacent faces of said extensions and the slide-ends are formed v the mold and holds it closed until the pin emerges therefrom.

Secured to and radiatlngvfrom the upper end of tubular post 4 is a series of arms 20` which support the upright cylinders 21, each of which overhangs a mold-support 7. Within each cylinder is a piston 21 from which depends a rod 22, and secured to this pis ton-rod is the upper plate 23 of the spring-plate mechanism. Secured to the lower end of cylinder 21 is head 24 from which depend the guiderods 24 upon which plate 23 moves, likewise lower plate 25 of the spring-plate mechanism carried bythe lower ends of rods 26 depending from plate 23, plate 25 carrying the neckmold mechanism, presentlyr to be described. An intermediate spring-plate 27, suspended on rods 28 from plate 23, bears downward upon the neck-mold during the pressing and blowing operations, as seen in Figs. 4 and 6.

Vertical compression of the spring-plate mechanism, or in other words, upward movement of plates 25fand 27 toward plate 23, is resisted by the 'coiled-springs on the platesuspending rods, which are arranged and operate in the usual manner. Secured to the lower end of piston-rod 22 is the plunger-cylinder 29, from the lower end of which eX- tends the hollow plunger 30, the lat-ter closely Vfitting an aperture in plate 27, and having an opening 30 in its lower end.

The neck-mold mechanism, carried by plate 25, consists of the divided neck-mold sections 31, of such formation as to closely iit and form upward continuations of the cavities oi.' 'press-mold 12 and blow-mold 13, resljwctiveiy. The' blow-mold sections are secured to slides 32 and 33 movable in guides 34 on plate 25, the slides being of the same formation as the blow-mold supporting slides, described above,- and provided with corresponding interposed gears 35, whereby they open and close in unison when either one of the slides is actuated. Depending from slide 32 is a pin 36 which projects into the cam-groove 37. of lever 37, fulcrunied to the lower-side of plate 25.v Thus, movement of the lever in one direction operates to separate the slides and open the neck-mold, while movement .in a reverse direction closes the mold and so holds it as to resist opening which is open on one side, as indicated at 419,-?.

and at its inner end is recessed at 42, the recess being of such form that in one position of the valve, ports 39 and 4() are in register and port 39 is open to the valve-casing through the open-side 41" of" the val'` as shown in iull lines in Fig. 16, while in ai f other position of the valve,' port 39 is open to the valve-casing and ports 39 and 40 are in registe'r through the valve-cavity 42, as indicated in dotted lines in the same figure. The valve is mounted on a stem 43, and the coileds ring 43 on this stem within the casing holds tiie valve tightly to its seat. Air under pressure is admitted to the valve-casing through pipe 44. Secured to valve-stern 43 is arm 45, which carries a roller -in its outer end for the purpose of riding on the fixed vertically irregular track 46, arranged at one side of the machine on uprights 46.

Movable vertically within plunger-cylinder 29 is a tube 47, to the lower end of which is secured the plug-rod 4Sl which normally closes the open lower end 30 of the plunger, as indicated in F ig. 13, said tube and rod being held normally depressed by the coiled spring 49. Tube 47 depends from the inner end of a tubular-arm 5U which projects through slot 29 'in cylinder 29, and at its outer end carries a roller 50 which travels over the short fixed trac i-section 51. Air under pressure is supplied to arm 50 through hose 52, which may conveniently extend from pipe 44.

Movable vertically in the upper portion of the inner end of arm 5() is the ported-valve 53 which is secured to the l'ower end of stem 54 carrying spring 54 which holds the valve normally raised and the cavity of arm 50 normally closed, as shown in Fig. 13. Vhen however during the pressing operation, arm 5() is raised by its traverse over track 51, as will presently appear, said arm is raised against thepressure of spring 49, and-with it tube 47 and plug 48, thus opening the lower end of the plunger, all as shown in Fig. 14. The same movement forces stem 54 upward against piston-rod 22, ithereby depressing valve 53 against the pressure ol" spring 54 and placing the interior olE arm 50 in registcr with tube 47, thus permitting thc air under pressure to Ilow downward through the latter and into the tubular plunger through side apertures 43"', and from thencel through the open lower end of the plunger' tor the purpose ol' expanding the blank. As the forming parts of the machine rotate with the mold-carrier or table` it is necessary IOO IIO
